COMPRESSORS, GAS TURBINES AND JET ENGINES QUIZ

15°C and 1 kg/cm²

20°C and 1 kg/cm² and relative humidity of 36%

Atmospheric conditions at any specific location

0°C and standard atmospheric conditions

p₁ p₃ = p₂ p₄

p₃/p₁ = p₄/p₂

p₁ p₂ = p₃ p₄

p₂/p₁ = p₃/p₂ = p₄/p₃

These knock out some oil and moisture

These act as reservoir to take care of sudden demands

These are used to dampen pulsations

These increase compressor efficiency

The exit velocities of exhaust gases are much higher than those in jet engine

All of these

The stagnation conditions exist at the combustion chamber

The combustion chamber in a rocket engine is directly analogous to the reservoir of a supersonic wind tunnel
